Python:
Python 2.7 (for the introductory examples)
Python 3.4 (optional; when developing Blender scripts with PyCharm it helps)
Tkinter (ActiveTcl)
PIL (source code and windows), for Macs: copy the contents of PIL_OSX.zip into “/Library/Python/2.7/site-packages” and the contents of libjpg.zip into “/usr/local/lib”, on linux you should be fine with sudo apt-get install PIL.
Blender and Geo-Coordinate converter:
Blender, pyproj (WIN, OSX_pyproj_py3.4) – either install it into “/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages” or “~Library/Application Support/Blender/2.72/scripts/modules”
